Siv dav hauv ntau daim teb ntawm silicon hlau
Txawm hais tias, tom qab txoj kev loj hlob ntawm xyoo tsis ntev los no, silicon hlau tau yeej qhov kev lees paub ntawm ntau cov neeg siv los ntawm kev tsim txiaj ntawm nws tus kheej lub zog, tau siv dav hauv ntau thaj chaw, tab sis vim tias silicon hlau tuaj yeem faib ua ntau hom, tab sis kuj muaj ntau txoj haujlwm, yog li feem ntau ntawm cov neeg siv ntawm silicon hlau tsis muaj qhov nkag siab ntau. Txhawm rau pom qhov xwm txheej no, cov tuam txhab ua lag luam silicon hlau yuav xaus cov lus thiab piav qhia kev siv cov khoom siv silicon, ntawm ib sab, tuaj yeem cia coob leej neeg, muaj kev nkag siab ntau ntxiv ntawm cov khoom siv silicon hlau, ntawm qhov tod tes tuaj yeem txuas ntxiv kev txhim kho ntawm silicon hlau.
1, abrasive, vim hais tias cov hlau silicon muaj lub zog siab, tshuaj lom neeg ruaj khov thiab ib qho tawv, yog li nws yog hom uas siv dav siv abrasive, tuaj yeem siv los tsim kev sib tsoo log, whetstone, coated abrasive lossis sib tsoo dawb. Nws yog tsuas yog siv rau kev sib tsoo iav, ceramics, pob zeb thiab lwm yam khoom siv tsis yog xim hlau, cam khwb cia hlau thiab qee cov hlau tsis sib haum, nws thiab cov khoom nruab nrab ntawm cov tshuaj tiv thaiv tsis muaj zog. Lub hardness ntawm silicon hlau yog thib ob rau pob zeb diamond, thiab nws muaj muaj zog hnav tsis kam.
2, cov ntaub ntawv refractory thiab corrosion resistant cov ntaub ntawv, vim lub siab melting kis ntawm silicon hlau (decomposition kub), tshuaj inertia thiab thermal poob siab ua hauj. Cov kev ua haujlwm tseem ceeb ntawm silicon hlau refractories xws li nias thiab sintering ntawm silicon hlau, nias thiab recrystallization ntawm silicon hlau, casting thiab recrystallization ntawm silicon hlau, thiab vapor deposition ntawm silicon hlau ntawm carbonaceous cov ntaub ntawv. Kev siv cov roj silicon muaj qhov kub tsis kam, siab zog, zoo thermal conductivity, cuam tshuam tsis kam, thaum kub kub tsis ncaj cov khoom siv cua sov, siv dav hauv metallurgical siab kub ua hauj khoom.
3, hlau thiab cov hlau metallurgical ntxiv, silicon hlau tuaj yeem siv los ua cov hlau zom thiab cov hlau tsis huv, uas yog, siv los ua deoxidizer thiab cam hlau ua haujlwm tsis zoo. Silicon hlau tuaj yeem decomposed nyob rau hauv molten steel thiab hnov mob nrog cov pa dawb thiab hlau oxide hauv molten steel los ua cov pa roj carbon monoxide thiab silicon uas muaj cov slag. Nyob rau hauv kev sib tsoo ntawm cov cam khwb cia hlau, ntau dhau ntawm silicon hlau yog feem ntau ntxiv los ua me me ntawm silicon rau hauv molten hlau, uas ntxuav cov qauv ntawm cov cam khwb cia hlau thiab txhawb qhov zoo tag nrho ntawm castings ua los ntawm nws.
Vim tias lub sijhawm tsawg, silicon hlau cov lag luam tsuas yog rau silicon hlau ob peb lub ntsiab thov chaw tau qhia, qhov tseeb, silicon hlau muaj lwm yam haujlwm, tuaj yeem siv rau lwm cov teb. Silicon hlau tuam txhab txais tos cov neeg siv khoom tshiab thiab qub los tiv tauj peb lub tuam txhab, peb lub tuam txhab tsis tuaj yeem tsuas yog qhia thiab muab ntau yam sib txawv ntawm cov khoom siv hlau silicon raws li koj qhov kev xav tau, tab sis kuj tuaj yeem teb koj cov kev tsis txaus siab txog silicon hlau, yog li koj tsim nyog dua, qhov tseeb daim ntawv thov ntawm silicon hlau, thiaj li ua tiav cov txiaj ntsig zoo.
